Using a electro-meridian pen on your wrist.

I got this nifty and futuristic looking meridian acupuncture pen.  I liked it enough to buy a bunch of them and have people do work on themselves.  Here is one way I have found to use it.

See the picture?  I have written numbers on my wrist which coordinate with the nerves we will discuss and treat here.
1. The Radial nerve, this nerve branches off the brachial plexus in the neck at about the 6th cervical vertebral space.  See below...

 Now, we also have to understand that the nerves to the hand come from the entire neck area (brachial plexus, cervical 4 through thoracic 1) but that when someone has a radial nerve or C5-6 nerve root problem we see it in the radial area.  Thumb...

2. the Median nerve... generally attributed to cervical 6 and 7, but you can really link back to the entire brachial plexus... if you really search through the roots, trunks, divisions, cords all the way to the major peripheral branches we are talking about here.

I have used some old x-rays I had to show you the number of the vertebrae and where the nerves branch from.



3. The Ulnar Nerve This one, on the pinky side of the hand comes from the lower part of the neck, C7 and T1 areas.  It is pretty definite in its origin unlike the other two above.  This nerve is easily pinched with trapezius or upper back and shoulder muscle tension.  It is also a common nerve to be affected with shoulder problems.

OK, so first we have to look at the wrist it self... The wrist is made up of an arch of bones called the carpal tunnel.  (Carpal refers to the wrist in anatomic terms).

Here is a cutaway view (rough diagram) of the carpal tunnel.

I took a picture of my left hand.  You will notice that in most anatomy books in the States you only see anatomy of the right side.  This is just convention.  You can see the left in any Gray's Anatomy book.  That is one of the reasons they are so cheap here.

The main points of the carpal tunnel are listed; the Flexor retinaculum, which is a tendon covering to help hold down all the tendons to the hand and fingers on the ventral/anterior side of the wrist (anatomical position).  It is where you would feel for a pulse.  (I did not draw in the arteries... )

The main bones of the tunnel.  These bones are movable and I will show you how in the video portion.
Notice the nerves, just about where I wrote the numbers on my wrist.  I will show you how to find them with the meridian acupuncture pen.

So now we know a bit about where everything is...
Here starts the problem.
I have been a chiropractor and acupuncturist for over 20 years, I have taught anatomy and physiology at the college level for over ten of them.   I have worked on plenty of people with nerve damage and pain in the hand and fingers and have rarely seen a true Carpal Tunnel Syndrome.  The anatomy can tell us why.  There is not much space in that tunnel and when you hold your wrist in a certain position for a long time, the joint can actually begin to change and the carpal tunnel can collapse or change enough to put pressure on the tendons and the nerve.

Now back to the pen.
I like it for what it is worth.  Which is not much.  It is a very basic electrical stimulation device, there is no way to change any of the parameters and I rarely feel any difference when I turn it up.  It has a display that goes from 1 to 9 and 0 being the off button.  You need a good grip on the thing and have moist skin for it to work.  You may get pinching or sensation in the treating hand (the hand you are holding it with,) that is because of poor contact.  Grip it tighter or move the depth of the probe.
But I figure, I have it, so might as well make some use of it.
I think it would be a good tool to find and stimulate peripheral nerves as well as motor-points in muscle.   It seems to have a pulse rate of about 2 Hz, but I don't know any of the carrier frequencies or micro amps etc.  It is a one AA battery which will get you a good 1.5 volts.  There is no step up transformer in it as far as I can tell, and I don't even know if that would even work.

Muscles of the hand:  well, this is a great item for that.  You can definitely stimulate them and get them to go.  There are really not many muscles in the hand anyway and they are so deep this pen just cannot really get to them.  The ones we can get are the thenar and hypothenar muscles.  They are on the thumb and pinky side of the palm respectively.

Muscles of the forearm and wrist.  Really you have to go up into the forearm as there are no real muscles you can get to in the distal wrist.  Lots of tendons and nerves.

So, what can it do?   The stim really does relax the muscle by pulsing it making it release stagnant blood and other fluids releasing the lactic acid and then allowing new blood and lymph to enter the area.  It burns up all the muscle fuel (ATP) and makes the body replace it.  It is a good idea to take some Calcium and Magnesium to help with the new needs of that muscle.

As for the nerve, it does appear to cause some anesthesia but this is just a numb feeling I have after using the unit.  There is no prolonged feeling of numbness, tingling or other paresthesia.
For the money I like it enough to promote it and suggest its use to patients.  It is a great tool for students who are learning nerve tracing and such so I would highly recommend it to chiropractic, acupuncture and advanced massage therapy students.  You can not only learn where the nerves are closest to the surface but what they feel like and their distribution.
